I installed a brand new Gen2 at our home today and one thing struck me odd during the installation. The AC transformer makes a constant buzzing sound like some old piece of electronics. Is that normal? It is in our garage so it isn’t something we have to listen to all the time, but I do spend a good amount of time working on things in the garage and prefer not to listen to it.

Hey Rick. Glad you’re excited about your new Rachio! As with our friends above, please contact Rachio Support at your earliest convenience (1-844-4-RACHIO) and we’ll gladly set you up with a new power adapter.
